What is 0.144 percent of 0.4 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 0.4 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 0.4 is 100%, so we can write it down as 0.4=100%.
4. We know, that x is 0.144% of the output value, so we can write it down as x=0.144%.
5. Now we have two simple equations:
1) 0.4=100%
2) x=0.144%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
0.4/x=100%/0.144%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 0.144% of 0.4

0.4/x=100/0.144
(0.4/x)*x=(100/0.144)*x       - we multiply both sides of the equation by x
0.4=694.44444444444*x       - we divide both sides of the equation by (694.44444444444) to get x
0.4/694.44444444444=x
0.000576=x
x=0.000576

now we have:
0.144% of 0.4=0.000576
